品牌与善因的匹配对善因营销的影响研究 总被引:1,自引:0,他引:1
通过文献回顾分析了企业与善因的匹配对善因营销效果的影响,结果发现,这种匹配对善因营销效果的影响不仅与消费者感知的匹配程度有关,同时还取决于消费者感知到的匹配类型(形象匹配与功能性匹配),以及许多调节变量(产品类型、购买情境、消费者对企业和善因的涉入及熟悉程度等)的影响。进而总结了目前研究的空白和不足,为未来的研究提出了建议。 相似文献

We study the business‐cycle behavior of segmented labor markets with flexibility at the margin (e.g., just affecting fixed‐term contracts). We present a matching model with temporary and permanent jobs (i) where there is a gap in the firing costs associated with these types of jobs and (ii) where there are restrictions in the creation and duration of fixed‐term contracts. We show that a labor market with ``flexibility at the margin'' increases the unemployment volatility with respect to one that is fully regulated. This analysis yields new insights into the interpretation of the recent volatility changes witnessed in the OECD area. 相似文献

This study provides empirical evidence on the impact of a minimum wage increase on employment of workers in the formal sector who have wages below the minimum level in Vietnam. Using the difference‐in‐differences with propensity score matching and the Vietnam Household Living Standard Surveys of 2004 and 2006, the article finds that the minimum wage increase in 2005 reduced the proportion of workers having a formal sector job among low‐wage workers. Most workers who lost formal sector jobs became self‐employed. 相似文献

This paper empirically investigates two dimensions of changes in firm behavior and performance before and after foreign direct investment (FDI). The first dimension is the difference between vertical and horizontal FDI. The second dimension is the effect of outward FDI on firms’ production and non-production activities in the home country. In our careful empirical analysis we use the propensity score matching method to show that the impact of outward FDI differs by dimension, that is, by FDI type and firms’ production and non-production activities. In particular, while horizontal FDI increases demand for non-production workers, vertical FDI increases demand for skilled production workers. 相似文献

This paper analyzes the relationship between local poverty and food manufacturing growth in Chile and Mexico using propensity score matching, differences in differences and spatial econometrics methods. We focus on food manufacturing as a sector with a number of characteristics that make it potentially pro-poor, and whose incentives for spatial distribution may either strengthen or dampen its poverty reduction potential. The overall results indicate growth in food manufacturing employment contributes to local poverty reduction. 相似文献

The 2000s witnessed the third poverty alleviation wave in China. Compared with its predecessors, the third wave distinguished itself by new interventions and redefined standards for the National Poor Counties. This paper evaluates the effectiveness of the new program using a data set consisting of 1,411 of China's western and central counties from 2000 to 2010. It combines the propensity score matching method with the difference‐in‐differences approach, which helps to avoid selection bias and track the policy impact on variables of interest at each time point. It is found that the non‐western local governments tended to manipulate data on income and output growth to maintain the special transfer payments disbursed exclusively to the National Poor Counties. It is also shown that the program failed to improve the infrastructure and sanitary conditions in general. 相似文献

In a random-matching economy of traders who maximize cumulative consumption (overtaking criterion), the stationary, Markov, Bayesian-perfect equilibrium is studied. At such equilibrium, two results hold: (1) perfect substitutability between current and future consumption implies a no-surplus condition; and (2) by the no-surplus condition, there is a nominal price at which all trades must occur. These results strengthen the seminal results of Ostroy (1973) regarding monetary bilateral exchange in two ways: the incentive compatibility of the equilibrium trading pattern is established and a less roundabout trading pattern enhances welfare by enabling consumption to occur more frequently. 相似文献

Logic Petri nets (LPNs) can describe and analyse the batch processing function and passing value indeterminacy in cooperative systems, and alleviate the state space explosion problem. However, the indeterminate data of logical output transitions cannot be described explicitly in LPNs. Therefore, Coloured Logic Petri nets (CLPNs) are defined in this paper. It can determine the indeterminate data of logic output transitions in LPNs, i.e., the indeterminate data can be represented definitely in CLPNs. A vector matching method is proposed to judge the enabling transitions and analyse CLPNs. From the marking equation and the proposed reachable tree generation algorithm of CLPNs, a reachable tree can be built, and reachable markings are calculated. The advantage of CLPNs can be shown based on the number of leaf nodes of the reachability tree, and CLPNs can solve the indeterminate data of logical output transitions. Finally, an example shows that CLPNs can further reduce the dimensionality of reachable markings. 相似文献
